16. Empty Positions
Empty positions on dial indicates no function is available on these
positions. The digital display will look like as in figure below.There are
three empty positions present on the dial.
Normally, it is difficult to access the middle busbar for current
measurement. With "Rotary mechanism for clamp jaws" it is easy to
access middle bus bar, while keeping display and keys facing towards the
user as shown in
figured on previous page.
Safe trigger mechanism
The conventional clamp meters have trigger mechanism either near to left
jaw or right jaw. While taking measurements on bare bus bar or bare
conductor the user’s hand comes very close to bare bus bar/conductor,
which increases the risk of electric shocks to the user.
Also in conventional clamp meters trigger is operated with single finger,
usually a thumb which causes fatigue to the user while opening or closing
the clamp jaws.
To over come the above mentioned problems, DELTA SOLAR
has a unique feature called "Safe trigger mechanism" in which trigger is
located at bottom side of the clamp meter and far away from the jaws
and hence the bus bar.
So user’s hand is at safer distance from bare conductors, hence
minimizes the risk of electric shock to the user. This is shown in
figure e.
Also trigger can be comfortably operated with more than one finger which
eliminates fatigue to the user.
For best accuracy keep the conductor at center of the jaw as shown
in figure e.
